Abstract：Objective To investigate the current clinical application of vacuum-assisted breast biopsy(VABB)in China,and to evaluate the postoperative pathological distribution of lesions across different breast imaging reporting and data system(BI-RADS)categories as well as diagnostic differences among hospital types,thereby providing a basis for standardized implementation and early diagnosis.Methods A questionnaire survey was conducted to collect clinical and pathological data of patients with BI-RADS category Ⅲ-Ⅳ breast nodules who underwent VABB at 39 Chinese hospitals between January 1,2023 and December 31,2023.Recorded data included the number of cases,BI-RADS classification,and postoperative pathological findings.Data were analyzed using SPSS version 26.0,and Z-tests were performed to compare pathological distribution differences between maternal and child healthcare hospitals and general hospitals.Results A total of 49 984 patients were included,among whom BI-RADS Ⅲ nodules accounted for 27461 cases,with postoperative pathology indicating malignancy in 321 cases(1.2％),benign tumors with atypical hyperplasia in 1 211 cases(4.4％),and absence of tumor components in 1 231 cases(4.5％),whereas BI-RADS Ⅳ nodules accounted for 22 523 cases,with malignancy in 1 460 cases(6.5％),benign tumors with atypical hyperplasia in 1 814 cases(8.1％),and absence of tumor components in 1 277 cases(5.7％).Comparison by hospital type showed that the malignancy rate for BI-RADS Ⅲ nodules was 2.5％in maternal and child healthcare hospitals versus 0.9％in general hospitals,with a statistically significant difference(P＜0.05),and for BI-RADS Ⅳ nodules,the proportions of all pathological categories also differed significantly(P＜0.05).Conclusion VABB of BI-RADS Ⅲ-Ⅳ breast nodules is an important approach for early breast cancer diagnosis and standardized pathological management.This technique has promotion potential in both tertiary and primary-level institutions.It is recommended to strengthen standardized training in ultrasound grading and optimize postoperative pathological workflows to improve diagnostic accuracy and clinical outcomes.
